The attached table is one that it is convenient for you to memorize as long as you're taking courses involving angles. For the inverse functions, find the column corresponding to the function, then look for the value in that column. The angle at the beginning of that row is the answer to your question.

8. \cos^{-1}(0)= 90^{\circ}=\dfrac{\pi}{2}

9. \sin^{-1}(1)= 90^{\circ}=\dfrac{\pi}{2}

10. \tan^{-1}\left( \dfrac{\sqrt{3}}{3} \right)=30^{\circ}=\dfrac{\pi}{6}

Multiply the polynomial x (3x-1)(2x+5) also what is the degree of the polynomial
Readme [11.4K]

Answer:

Result after multiplication of polynomial is: 6x^3+13x^2-5x

Degree of polynomial = 3

Step-by-step explanation:

The given polynomials are:

x(3x-1)(2x+5)

In order to multiply the given polynomials we have to work step by step. First of all the polynomials in the bracket will be multiplied and then their result will be multiplied with x.

So, multiplying the polynomials in round brackets first

=x(3x-1)(2x+5)\\= x\{3x(2x+5)-1(2x+5)\}\\=x\{6x^2+15x-2x-5\}\\=x(6x^2+13x-5)

Now multiplying with x

= 6x^3+13x^2-5x

Degree of a polynomial is the highest exponent of variable in the polynomial.

In the acquired result, the highest exponent of x is 3 so the degree is 3.

Hence,

Result after multiplication of polynomial is: 6x^3+13x^2-5x

Degree of polynomial = 3

I need to know what this answer is<br><br><br>3. Write the expression 175 using radicals. ​
Rus_ich [418]

Answer:

5√7

Step-by-step explanation:

What we want to do is first just put the 175 in a sqrt like this:

√175

Next we do prime factorisation to try and simplify further.

         175

      /          \

   25            7

  /     \

5         5

We can figure out that this out √5^2 times 7

we can cancel the sqrt and the squared and simplify to 5√7

So there is your answer, 5√7.

If you have any questions feel free to ask. Also for the prime factorisation the formatting may be off, sorry for the inconvenience and have a good day!

Can someone answer this question?
KonstantinChe [14]

Answer:

No solution.

Step-by-step explanation:

(1/12)^-2b * 12^(-2b + 2) = 12

1/12 is basically the same thing as 12^-1.

12^(-1 * -2b) * 12^(-2b + 2) = 12

12^2b * 12^(-2b + 2) = 12

12^(2b - 2b + 2) = 12

12^2 = 12

Since the answers don't match up, the answer will be no solution.

Hope this helps!
